In 2018/9 was self-employed, ended self-employment in Nov 2019, and have now been furloughed. Tax return for 2018/19 was sent in in Jan.
I got a message from HMRC on 10th March saying that I needed to confirm my actual income for 2018/9 (it was previously an estimate) by 31st March, but I havent been able to get through to them.
I'm getting substantially reduced furlough, as its apparently based on average earnings over 12 months (and I've only been employed for 4 months), so tax credits are fairly essential at this time and I'm worried my tax credits are going to get cut off.
Is there any other way to update the tax credits people on my 2018/9 income other than phone?
